Objective Determination of Minimum Engine Mapping Requirements for Optimal SI DIVCP Engine Calibration

By Pete J. Maloney, MathWorks


In response to marketplace demand for increased engine performance and economy, spark-ignition (SI) engine applications with dual-independent variable cam-phaser actuators (DIVCP) are now commonplace. In this paper, the minimum number of test measurements required to optimally calibrate the steady-state spark advance and cam-phaser settings of a SI DIVCP engine is determined using a high-fidelity model of a 2.2L SI DIVCP engine with predictive combustion capability as a basis.
